No, there is no separate cut-offs in NDA.

As compared to NDA AFCAT is somewhat simple in question levels. So, it is the best option to choose IAF.

You can prepare using the study materials available online. Purchase previous year sample papers and practice.

There are plenty and I repeat plenty of books for such exams available online and on e commerce websites. Just type in and you will get all the books.
